GEORGE A. HYDE, OF LONSDALE, RHODE ISLAND.

GAS-GOVERNOR.

To all whom it may concern:

Be it known that I, Gnonou A. HYDE, a citizen of the United States,residing at Lonsdale, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements inGas(}overnors, of which the following is a specification.

My invention relates to a device for regulating the force of supply asit comes from a meter; and the object in view is to provide a device ofthis character with means which is operated automatically by the evervarying initial or high pressure supply, to cause said initial or highpressu a supply to become reduced to a proper degree of low pressure andthereby to obtain a perfect combustion at the burners or points ofconsumption for either illuminating or heating purposes.

My invention consists of the novel construction, arrangement, andcombination of parts, as hereinafter described and claimed.

In the accompanying sheet of drawings, Figure 1 represents a sideelevation of my improved gas governor, and, Fig. 2 is a sec tional viewof the device, as constructed in accordance with my invention.

Like reference characters indicate like parts.

l /i y improved gas governor has a casting in the form of a tubular bodya whose top is closed, as at c and a cupshaped recep tacle a whichsurrounds and extends il'rom the middle portion of said body to a pointabove its said closed top.

The receptacle o oi the body a, is designed to contain a quantity ofmercury, as I). A cap 0 has an annular flange c" which is intcriorlyscrew-threaded to engage an exterior screw-thread formed on the upperportion of the receptacle o Beneath the re ceptacle a the body a has athreaded hub a to engage the end of the gas discharge-pipe 7) whichleads to the burners.

The bottom of the body a is interiorly screw-threaded to engage thethreaded end of a tubular member (Z. This member (Z has, at its middlepart, a circular beveled valveseat (Z and above this seat is mounted athin cylinder 0 which fits in the upper portion of the bore of themember (Z and of a lieight to have its top :t'ace come in a plane withthe center of the gas discharge-pipe p.

Specification of Letters Patent.

Application filed March 4, 1910, Serial No. 547,334. Renewed March 18,1912.

Patented Oct. 8, 1912.

Serial No. 684,535.

Each end of the cylinder 0 has an integral bar, as at c, a extendingdiametrically across said cylinder and each bar is provided with acentral opening to loosely receive therct-hrough a valve-rod j. This rodf passes loosely through an opening at formed in the closed top 01. thebody a, and on the upper end of said rod is made last a hell 9 whosesides are SHlMDGIQMl in the mercury 12. A circular valve 71. is made ilast on the bot tom of the rod f, and said valve has a bevel face itdesigned to come in contact with the scat (Z of the member (I. The valveh loosely fits within the lower bore of the member (Z and is providedwith a depending screw 2' to act as a support for disk-weights 7', j.\Vithin the cylinder 0 a spiral tan Z: having a central integral hub hloosely surrounding the valve-rod f and ot a length to extend betweenthe bars 0 c of said cylinder. The lower end ol. the member (Z isexteriorly screw-threaded to engage thereby with a coupling nut Z, forsecuring the flange m of the gas inlet-pipe m to the device.

A. pct cock in is mounted on the cap 1: to permit the escape ol whatevergas there may be within the chamber 0 surroumling the bell prior tooperation ol the device.

Assuming the device to be in operation: The high pressure gas comes fromthe meter through the inlet-pipe m thence through the valvechamber 1,through the'port '1', thence against the spiral tan is and causing thelatter to revolve, but only at a speed relatively to the varying degreeof existing high pressure, thus when the gas has passed from the faninto the chan'iber s, the pressure will have become reduced to a properlow degree to pass through the dischargepipe 7) to the burners or pointsof consumption.

As the pressure from the meter is constantly varying the tan in acts asa governor to control this pressure, by simply revolving fast or slow,in accordance to the amount of pressure passing through said fan. Thisfan 7.: also acts as a mixer to agitate and enrich the volume of gasfrom the meter and bring said gas to a reduced state for a perfectcombustion at the burners.

Whenever the low pressure in the chamber .9 reaches a high degree itpasses through the opening a" and causes the hell 1 to rise and therebycloses the valve 7L upon its seat.

The mercury 6 acts as a seal to prevent any excessive pressure of gasfrom the opening a to surround the exterior of the bell y top, acup-shaped receptacle carried by said casing adapted to contain mercury,a cap secured. on the receptacle and provided with a vent, a verticaltubular member having its upper end secured in the lower end of saidcasing, said member having a beveled valveseat surrounding a port, avalve rod extending loosely through the top of said casing and throughthe port in said tubular memher, a bell secured on the upper end of saidrod between the cap and the top of the easing and having its sidessubmerged in the mercury in said receptacle, a valve secured on thelower end of said rod and having a beveled face to contact with saidbeveled valve seat, a weight suspended from said valve, a gas inlet pipein open communication with the lower end of said tubular member, andpressure reducing means in said casing through which said rod extends.

2. In a device of the character described, the combination with avertical tubular casing provided with an outlet intermediate its endsand having a top, a cup-shaped receptacle carried by and surrounding theupper portion of said casing and adapted to contain mercury, a capsecured on'the receptacle and provided with a vent, a vertical tubularmember having its upper end secured in the lower end of said casing andprovided intermediate its ends with a valve seat surrounding a port insaid member, a valve rod extending through the top of said casing andthrough the port in said tubular member, a bell secured on the upper endof said rod between the top of said casing and the cap on saidreceptacle and having its sides submerged in the mercury in saidreceptacle, a valve secured to the lower end of said rod to close theport in said tubular member, a weight suspended from the valve, andpressure reducing means arranged within the casing and tubular memberabove the port in the latter. r

In testimony whereof I aflix my signature in presence of two witnesses.
